Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13, can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(4, 9, 26)
(2, 8, 20)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (13, 2, 30).
(4, 9, 26) → (4 + 9) × 2 = 26
(2, 8, 20) → (2 + 8) × 2 = 20
Similarly, (13, 2, 30) → (13 + 2) × 2 = 30
